I don't know wether it's the fact that a lot of the raidguilds are run by 20-25 year olds and they're just trying too hard and overcompensating too hard to try and look professional and serious, but there is seriously nothing that I find more useless, pointless than raidgroups that ask applicants to fill out applications.
I guess I'm much more practically oriented myself, and if your raidgroup badly needs to fill up a spot with a healer or a ranged DPS ... why not just throw them a guild-invite and give them a recruit rank and let them show you if they are what you're looking for or not. If you're a majorly popular guild that gets multiple applications a week, sure, then I can understand this tool to try and weed out applications... But there are so many guilds that barely get 1 application a month, 1 application every week AT BEST ... who still insist that the application form is used and that people are to sit around like lemons until the young adult / teenager asses of officers manage to get together (if they remember to) to discuss the single application on their forum...
The recruit / trial rank in guilds is seriously underused. Even while I was in world top progress guilds ... 99% of the trials (people that thus got through the application process) also ended up passing their trial (because they usually were the only application). Even if they sometimes didn't perform all that well... I bet there would've been in many cases better recruitment chances for better people if they didn't ask people to fill out applications. I know many of my friends and people that used to be in world top guilds can totally not be arsed to fill out applications, because 1. They know they're definately great and experienced players. 2. Don't want to be subjected to the arrogance of ... some of the guilds out there with very snotty attitudes. (Last week for example one of my friends got told to compete against the DPSers of another guild on the training dummies in Orgrimmar. He used to raid with Method for a good long time, he was ilvl 470 something... They put him up against mages and warlocks in full epic gear ilvl 490 etc. He does about 70k DPS ... their guys do 100k DPS ... then their officer replied with "you suck, l2play, we can't use noobs in our guild... Your application is denied.") People that were observing it and knew who this person was were facepalming ... luckily another guild that also needed to fill a spot threw him a guild-invite and this week alone he progressed several bosses past the guild that had the elitist attitude and rejected him (based on a very arbitrary test, not to mention the inaccuracy of it. ... Not that this means much, it's just an anecdotal story with a touch of irony I guess).
Now... cross realm applications I might understand too. Or applications of people who secretly still want to stay in their guild while trying to get into another. But when this isn't the case... djeez. Why so serious? Get more practical, don't overcompensate on redundant bureaucratic matters.
At least that's my opinion.
